Want one-click selection? AC/DC low-power power supply modules also have “magic oil”!

[Introduction]Many Electronic engineers are familiar with the selection of DC/DC power supply or switching power supply, but they have a headache in the selection of low-power AC/DC power supply modules – neither the DC/DC power supply has a clear classification, nor the switching power supply standard Universal. In small and medium-sized equipment, the common power is tens of watts, but the AC/DC power supply at the front end needs to face problems such as working conditions, EMC, volume, and packaging.

In fact, it is very simple to easily solve the problem of AC/DC low-power power supply selection. You only need a highly integrated power supply product with excellent performance. , Ultra-small size, ultimate performance, 305 full working condition AC/DC module power supply “LDxx-23BxxR2 series”, can be widely used in industrial control, power, home appliances, instrumentation, communications and civil and other fields.

The industrial environment is relatively harsh. Next, the typical application of LD-R2 in industrial environment will be given to illustrate how LD-R2 can easily solve the above problems.

1. Application of LD-R2 in industrial controllers

The ultrasonic welding device converts the current 50/60Hz electric frequency into 20KHz or 40KHz electric high-frequency electric energy through a transistor functional device, and supplies it to the converter. It consists of generator, transducer, horn, welding head, press, parts support tooling and so on.

Ultrasonic welding has high requirements on the output power of the power supply, and the output power of the power supply directly affects the quality and efficiency of ultrasonic welding.

Jinshengyang module power supply LDxx-23BxxR2 series of medium-power and low-power power supplies are fully covered to meet the power requirements of ultrasonic welding; meet IEC/EN/UL62368/EN60335/EN61558 standards, isolation withstand voltage 4000VAC; mean time between failures (MTBF) > 3200 ,000 h; with output short circuit, overcurrent, overvoltage and other protection functions; wide voltage range 85~305VAC/100-430VDC meets global voltage requirements, and standard voltages such as 110/220/277VAC are applicable.

2. Application of LD-R2 in industrial environmental monitoring equipment

The online water quality detector is a common environmental monitoring equipment, which is responsible for the digital management of the whole process of water monitoring and analysis, data acquisition and transmission, and remote monitoring, which promotes the informatization and modernization of water quality monitoring and management.

The online water quality monitor is used in the field environment, where it is easily damaged by outdoor lightning surges, and it has high requirements on the outdoor working temperature range.

Jinshengyang module power supply LDxx-23BxxR2 series has low ripple and noise, stable power supply voltage and is not easily disturbed. It can directly supply power to detection sensors, and is friendly to sensor sensitivity. The operating temperature range is -40°C to +85°C.

3. Application of LD-R2 in industrial communication equipment

Industrial switches are Ethernet switch devices used in the industrial control field. They have carrier-grade performance characteristics and can withstand harsh working environments. The product series is rich and the port configuration is flexible, which can meet the needs of various industrial fields.

The main power supply of the industrial switch can choose LD90-23B12R2, the power is 90W, the design is compact, the no-load power consumption is as low as 0.1W, and the efficiency is as high as 87%.

In addition, LD90-23BxxR2 continues the advantages of LD-R2 series, balances the high pursuit of volume, performance and efficiency, and has the advantages of wide operating temperature range -40℃ to +85℃, small size and high reliability.

In response to the refined needs of the industry, Jinshengyang fully considers the product size and appearance for the majority of users. 305 full working condition AC/DC module power supply LDxx-23BxxR2 series has a variety of package options, including plug-in, wiring and other package forms, to meet the needs of various sizes and pins on the market.

On the road of making power supply, Jinshengyang constantly adheres to technological innovation, continues to iteratively upgrade products, solve application problems in different environments, create new industrial standard power supplies, and provide users in different industries with worry-free and easy-to-use power products.
